TYPOGRAPHICAL MACHINE.

Application filed November 16, 1925.

This invention relates to improvements in typographical machines and more particularly to an improved cooling system or means for the molds of such machines.

The molds of typographical machines, after a short term ot use, tend to become overheated so that the castings formed in them no longer maintain their solid and compact character with the sharply defined outlines that are characteristic of castings which are cast in properly cooled mold. The castings in an overheated mold tend to become honey-combed, pitted, and spongy with their faces ci blurred and imperfect outlines.

rlhe object or" the present invention is to provide an improved cooling system or means which will maintain the molds properly cooled so that Aperfect castings may be cast therefrom.

A further object of the invention is to provide an improved cooling system for the purpose referred to which can be readily applied to the standard typographical machine equipment without interference with the general 'form and arrangement of the parts thereof.

rllie invention comprehends an improved typographical machine mold in which the molding devices or molds proper on the moldwheel have interior channels or cooling Huid courses in the walls thereof and means is provided for conductinga cooling fluid to and 'from said interior channels or cour es. The invention further contemplates an improved'cooling system of this kind in which the interior channels or courses oi the several molding devices on the mold wheel are connected one with an- 'other in series to provide for the circulation oi the cooling fluid throughout the interior channels or courses of the several molds from one to another.

The invention, with other objects and advantages thereof, and the particular construction, combination and arrangements of parts comprising the same, will be underfstood from the hereinafter contained detailed description, when considered in connection with the accompanying drawings,

forming part hereof and illustrating ernbodiments of the invention.

While speciiic embodiments of the invention areV illustrated' in the drawings,r it will of course be understood that changes and modifications may be made in the particular constructions shown, and the invention may be embodied in other forms, as will appeal to those skilled in the art and falling Within the scope of the appended claims, without departing from the spirit of the invention.

Referring to a detail description of the particular embodiment of the invention ily ing or hanger 3.' The axle 2 at'the end has.

, a reduced portion 4 upon which the hub of and return channels 26, 27, providing for the circulation of the cooling fluid through the interiorfluid cooling coursesof the several molding devices from one to another.

Cold water or any other suitable cooling fluid mayV be employed as the cooling medium, this being supplied to the intake pipe V21 under the proper pressure from any convenient source. The water from the supply pipe 21 entering the channel 17 through the inlet 19 passes to the annular chamber 15, and therefrom through the channel and the radially extending channel 25 in the mold wheel to the port 27, and thence through the interior cooling courses of the several molding devices, and returning from the outlet port 42 of the last mold of the series through the port 28 to the radially extending channel 26, the longitudinally eX- tending channel 24, the annular chamber 16, and channel 18 to the exhaust pipe 22, which latter may lead to a receiving tank or waste pipe (not shown).

The interior radially extending channels 25, 26, :the interior connecting channels 43, 44, 45,- in the mold wheel, and the interior channels 35, 36, 37, 38, l39, and 401l of the molding devices are conveniently provided by drilling intersecting holes as shown, and closing the outer end of the holes by screw plugs 46.

Means is provided whereby if it is. not desired to use a complete set of mold devices "f on the mold wheel, a lesser number of molds channel 48 and ports 49, 50, leading fromthe ends of said channel to the rear face of the' bloclrand adapted to align and communicate withv either of the pairs of' `ports 22E-43a, 4311-449', 44h-45a, 45h-27, which lead inwardly from the. outer face of the mold wheel 1. As will be understood one or more dummy mold members 47 may be employed and substituted for one or more of the regy ular molding devices on the mold wheel, the dummy mold members 47 being secured to the mold Wheel 1 by screws 51, which enter the openings in the mold wheel that are provided for and engaged by the securing screws 34 of the regular molding devices.

In Figures 15, 16, and 17 is illustrated a modified construction that provides for the circulation of the cooling fluid through the .interior cooling fluid courses of the molding devices in series, and also for the circulation of the cooling fluid thro-ugh the interior cooling fluid course of one or more of theY molds. This modified construction is the saine as that previously described and illustrated in Figures 1 to 12 except that instead of a single supply and return passage 25, 26, 23, 24, leading from the annular chambers of the inner core or spincie through the core and mold wheel, separate supply and return channels in the moldy wheel 1 and ,the core member or spindle are provided for each of the molds, and valves are provided in the system for cutting oft the circulation of the cooling fluid from any of the molds. In these views, 52 designates the mold wheel, 53 the wheel aXle,54 the 'bearing for the axle, and 55 the core or spindle. 56-57, 58-59, 60-61, 62-63, are the separate interiorv inlet and return passages in the mold wheel'for the several molds,

separate interior inlet and outlet channels in the axle connecting the first mentioned iets of passages with the annular chambers 7 2, 73, in the'core member 55, 74, 75, V76, and 77 designate rotary plug valves controlling the Eil connecting passages r78, k79, 8O and 81 be- A tween the molding devices, and 82 desi gnates similar valves to control each of the separate palrs of inlet and return channels 56-57,

Y58-59, 60-61, and 62-63.

It will be noted that the special construction and arrangement of parts hereinbeforo set forthV provides for the circulation of a cooling fluid interiorly of the walls ofthe mold devices or molds `proper completely around the -mold cavity. VThe improved cooling system is of such a character as to be readily applied to standardtypographical machine mold equipment, the molding cle--v vices or molds proper being of general standard form and interchangeable.
